About Ganzoni Equation
Understanding Iron Deficit Calculation
The Ganzoni equation calculates total iron deficit by considering body weight, current and target hemoglobin levels, and iron stores. This method is widely used for determining appropriate iron replacement dosing in iron deficiency anemia.
Formula:
Total iron deficit (mg) = Weight (kg) × (Target Hb - Actual Hb) (g/dL) × 2.4 + Iron stores (mg)
Where:
- 2.4 is a correction factor including blood volume
- Iron stores = 15 mg/kg (up to 500 mg)
